octeontx2-af: Enable inner IPv4 checksum and its error code

Browse Source 
This patch enables the inner IPv4 checksum and
defines the error code for Rx inner and outer checksum errors.
Setting ERRCODE as 1 so that CQE descriptor can be embedded
valid checksum error code and the driver can interpret
checksum error as ERRLEV = LID + 1 and ERRCODE = 1.
